Figure Lengend Snippet: Mechanism of TRIM46 deficiency-induced DNA damage, enhancing the sensitivity of DDP in NSCLC by regulating Akt signaling pathway. (A) TRIM46 expression was positively associated with DDP resistance in NSCLC tissues. (B) TRIM46 overexpression significantly suppressed DDP-induced apoptosis and enhanced DDP resistance in A549 cells. (C) TRIM46 knockdown induced DNA damage by modulating the protein levels of p-AKT, RAD51, caspase 3, and cleaved-caspase 3, thereby resulting in cell proliferation inhibition in NSCLC cells. (D) TRIM46 knockdown increased the sensitivity of xenograft tumors to DDP treatment. NSCLC, non-small cell lung cancer; TRIM46, tripartite motif 46; DDP, cisplatin; p-, phosphorylated.
